Extend the DVB frontend parameter enums with additional values specified
by the DVB-C2 (ETSI EN 302 769) and DVB-S2X (ETSI EN 302 307-2)
standards to be ready for frontend drivers for such receivers.
While most parameters will be "read-only" due to being autodetected by
the receiver and only being reported back for informational purposes,
the addition of SYS_DVBC2 to the delivery systems enum is required,
because there are DVB-C2 capable receivers which are not capable of
DVB-C/C2 autodetection and thus need this enum value to be explicitly
instructed to search for a DVB-C2 signal.
As for DVB-S2X, as that is an extension to DVB-S2, the same delivery
system enum as for DVB-S2 can be used.
Add the additional enum values and comments to the documentation.

The only upstream driver using the API described there is the
av7110 driver.
As the driver was moved to staging, move the API bits to staging
as well.

The conversion tools used during DocBook/LaTeX/html/Markdown->ReST
conversion and some cut-and-pasted text contain some characters that
aren't easily reachable on standard keyboards and/or could cause
troubles when parsed by the documentation build system.
Replace the occurences of the following characters:
- U+00a0 (' '): NO-BREAK SPACE
as it can cause lines being truncated on PDF output
- U+2019 ('’'): RIGHT SINGLE QUOTATION MARK
- U+201c ('“'): LEFT DOUBLE QUOTATION MARK
- U+201d ('”'): RIGHT DOUBLE QUOTATION MARK

There are lots of tables that are not properly displayed
in LaTeX/PDF.
Fix the tablecolumns, add longtable where needed and LaTeX
formatting macros, in order to address such issues.

Sphinx 3.x broke support for the cdomain.py extension, as the
c domain code was rewritten. Due to that, the c tags need to
be re-written, in order to use the new c domain notation.

There are some files that are dual licensed GPL and GFDL.
As SPDX v3.10 gained support for GFDL-1.1 with no invariant sections:
https://spdx.org/licenses/GFDL-1.1-no-invariants-or-later.html
Let's remove the dual license text, replacing them by:
SPDX-License-Identifier: GPL-2.0 OR GFDL-1.1-no-invariants-or-later

SPDX v3.10 gained support for GFDL-1.1 with no invariant sections:

Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee38 ("docs: Create a user-space API guide").
As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.
Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.
